I agree with Jim, the SL materials will get there. But I don't think the SLA process will penetrate production very far. It's too expensive and labor intensive. I think machines more like 3D's Invision and hybrids are the ticket to manufacturing.

I have to add that this is my personal opinion, not necessarily that of my employer.

Yes! Our SL resins are currently in use as end products. Also, look at the new materials that have come out in the past 4 years, including the one you mentioned. What a difference! The industry went from several General Purpose brittle resins to a wide range of SL materials with unique and different mechanical properties. At this years SLA/SLS User's conference, more SL resins were introduced than ever before. Just wait and see what is developed in the next 4 years. But the SLS technology is also advancing in accuracy and materials. Nothing stays the same!
